highly significantP = 9.999e −05
Beta diversity among sampling years was highly significant for all bird species ( n = 167, R = 0.175, P = 9.999e −05 ; Supplementary Fig. 8c ) and when subsetting by only sandhill cranes ( n = 122, R = 0.106, P = 9.999e −05 ), but not when subsetting for only non-crane bird species ( n = 45, R = −0.70, P = 0.905).
